DANIEL J. DAVIS, OF CHICAGO, ILLINOIS, ASSIGNCR OF ONE-THIRD TO STEPHEN J. DAVIS AND ONE-THIRD TO ALBERT J. DAVIS, BOTH OF CHICAGO, ILLINOIS. I

BOTTLE-FILLING- APPARATUS To all whom it may concern:

Be it known that DANIEL J. DAVIS, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, has invented new and useful Im rovements in Bottle-Filling Apparatus, of W ich the following is a specification.

This invention relates to improvements in a bottle filling apparatus for general urposes, but is more especially intended for the use of dairymen and dealers in filling milk.

and cream-bottles; and has for its object to provide an apparatus of this character wherey the operation may be accomplished with facility and in accordance with sanitary conditions and requirements.

The ap aratus will ordinarily be made up of a num er of-individual filling devices'arranged in series in accordance with the capacity required in fillin a number of bottles or vessels simultaneously. It will be under stood however, that the apparatus may consist of one, two, three or more individualfilling devices, a bottle'being shown in position which corresponds to the relative position of the series shown in Fig. 1; and Fig. 3 is a vertical section showing the different parts in their opposite or abnormal position from that shown in Fig. 2.

A may represent a receptacle or reservoir suitably sup orted in posltlon and wh ch contains the 1111 k or other liquid product to be I run into the bottles.

I. A socket-piece B is rigidly secured to th receptacle A, one for each individual filling device when arranged in series. The up er end of a combined filling-tube and ya ve stem 0 has a screw threaded engagement with the socketiece as at b, Fig. 2. A vertically slidable s eeve D is telescoped on the filling-tube C and is provided with a shoulder 4 for a bearing support of the lower end ofa spring 5 encircling the socket B and the S eeve D. The upper end of-this spring bears Specification of Letters Patent. Application filed May 15. 1906- Serialllo. 260.452.

against a flange 6 formingapart of the socketplece. The upper portion ofthe sleeve D closel conforms to the fillingtube, the lower part eing of a greater diameter and provides for an annular s ace 7 therebetween into which the liquid ows from the fillingtube through port or slot 0 enings 8 on its passage to the outlet or discharge end as indicated by the arrows in Fig. 3. a

It will be noted that the lower end of the sleeve D is disposed a suitable distance beneath the openlngs 8; and, as will be readily seen, by glancing at the arrows in Fig. 3, the

advantage of these openings 8, in connection with the disposition relative thereto of the lower end of the sleeve D, isthat the fall of p the liquid through the filling-tube C is broken at the point of said openings, and is caused to,

flow in a sheet against and down the interior walls of thesleeve D, thence onto the beveled surface 11, and thence down the interior walls of the bottle, all as graphically illustrated b the arrows in Fig. 3.

It wil be understood that the description of one individual filling device will answer for the series, the same reference characters being a plied to duplicate parts.

A dis -valve 9 is mounted on the lower end 'It will be understood by this arrangement that the valve 9 occupies a stationary position, the valve-seat 10 being movable away from and towards the valve in opening and closing the fluid passage coincident with that of .the vertical movement of the sleeve D. The lower end of the filling-tube is provided with a chamber 12, just above the shut-off valve 9, in which is loosely laced a ballvalve 13, normally seating ownward and closing, the air escape opening 14 through the valve, 9-. The wire guards 15 prevent the ball-valve from back seating and closing the passage leading'out through the air-tube 16. Said air tube is threaded at its lower end, at 27, into the bore ofthe filling tube below the enings 8, thus closing the lower end of the fifling' tube to the passage of liquid. The tube 16 may be readily removed to facilitate cleaning.

air. A body of foamforming on top A conical flaring cap 17 is threaded on the lower end of sleeve D and may be moved upward or downward thereon in properly adjusting the position of the same with reference to the height of the bottle and the relative position of the valve 9 in the neck in filling the bottle to a certain level. The chamber 18 in the conical cap provides for the insertion of a cushioning air-tight gasket 19. This gasket is provided with a rim or lip edge 20 which extends over and has a close fitting bearing with the exterior neck of the bottle 21 when contacting the same in the operation of filling.

The bottles to be filled are arranged on an endwise movable tray 22, which is in turn supported on a vertically movable table or" platform 23 which may be raisedupward. at the proper time by means of a foot-treadle and connections 24, as shown in Fig. 1. The bottles to be filled are placed on the tray 22, one under each individual fillin -tube; the relative normal position of the ottles and filling mechanism being clearly indicated in Figs. 1 and 2. The lowermost position of the valve 9 in the neck of the bottle will be just below the shoulder 25 on which the paper closing cap seats. This is to permit of a bot-i tle belng filled close up to a level with the shoulder 25 at one operation, so. as to leave no air s ace between the cap-and surface of the The annular air-space 26 between the flexible gasket 19 and the shoulder 25 on the interior neck of the bottle will ordinarily prevent the milk from coming in consides of the bottle in a thin sheet and causes,

the same to follow'the sides down to the bottom as indicated by the arrows. The milk on other fluid entering and followin down the sides of the bottle does not boi up or foam as it would if the milk flowed down the center of the bottle and struck the bottom with more or less force and mixing with the of the milk prevents the bottle being fille to the desired level at the one operation. The milk flowing'down the sides of the bottle leaves the center space clear so that the air is grad ually displaced and forced upward asindicated by the arrows, and expelled through the air-tube into theatmoshere.-

In practical working the ottles are raised upward and coming in contact with the cushioning askets forces the'sleeve inclosing the milk tu e upward against the pressure of,

its spring and at the same time moves the valve seat away from the valve and opens the milk passa e which allows the milk to flow into and fil the bottles. When the bottles are lowered and the pressure relaxed the sleeve carrying the valve-seat is returned to its normal'position, the seat on aging the valve and shutting off the flow. ith a very little experience the operator will be able to shut off the flow instantly at the right moment and fill the bottles flush with the shoulder on which the closing caps rest. I

Having thus described my invention, what I claim is:

1. In a bottle-filling apparatus, a filling, tube adapted to be connected with a source of supply andhaving lateral openings through its lower portion, the tube being closed be low said openings, a valve secured rigidly to said tube below said openings, a sleeve inclosing and having a vertlcal movement relative to said tube, being spaced laterally therefrom in the region of and beneath said openings, there being thusformed an annular discharge-chamber between the tube and sleeve, and the lower end of the sleeve bein disposed a suitable distance beneath sai openings and constituted as a seat for closing against said valve, and in air-tube adapted to permit escape of air within the bottle.

2. In a bottle-filling apparatus, a fillingtube adapted to be connected with a source of supply and having lateral openings through its lower portion, an air-tube securedwithm said filling-tube and closing the same below said openm 's, an ou-tWard-projectin valve.
